Kosmos Oil Lamp operating tips.
1. We recommend using regular clear lamp oil, clear 150° kerosene, or synthetic kerosene only. Paraffin oil in the U.S.A.
(Ultra-Pure, Nowell’s, etc.,) has a flash point
over 250°, and will not burn properly and will clog the wick in a Kosmos Lamp. Once the wick is clogged, it must be replaced.
2. Remove the chimney and carefully unscrew the burner, being careful not to use the burner stem or thumbwheel as a lever. Even trimming of the wick is important and is most easily accomplished by exposing a bit of DRY wick above the wick tube, adjusting wick so it is even all around, and burning the wick dry until it is evenly consumed all around.
3. Fill the oil container approximately 90% full. It is also important to keep the lamp no less than 1/3 full. If the fuel level is too low the flame will begin consuming the wick.
4. Screw the burner back on to the oil container and let the wick become fully saturated – approximately 30 minutes – before lighting the lamp.
5. Light at minimal flame, quickly replace the chimney and keep the flame low for a few minutes until the cold glass has had time to warm
to prevent the chimney from cracking, then adjust the flame to the
desired level. (Flame at highest level should be around 1” tall.)
6. Lamps direct heat upwards so allow at least 24” clearance above chimney to combustible surfaces. Use a smoke bell to help deflect ascending heat.
